Oquendo loses his 0: Heavyweight contender Fres Oquendo, the Chicago-raised Puerto Rican native, went from 22-0 to 22-1 Saturday after being stopped by David Tua in the ninth round of a fight Oquendo was winning on points by jabbing and moving.

Watchful of Tua's heralded left hook throughout, Oquendo got wobbled with a solid right to the head and then foundered as Tua swarmed him with a barrage of punches, landing another flush right before referee Dave Johnson halted the bout.

Vowing to "be back" and learn from his first pro loss, Oquendo said, "People make small mistakes and he takes advantage of them."
